Description

4-Nitrophthalic Acid Anhydride (CAS: 5466-84-2) is a high-purity organic compound with the molecular formula C₈H₃NO₅. This yellow crystalline powder is widely utilized in research and industrial applications due to its reactivity as a phthalic anhydride derivative. It serves as a key intermediate in the synthesis of dyes, pigments, and advanced polymers. With a melting point of approximately 165-170°C, it is soluble in organic solvents like acetone and dimethyl sulfoxide (DMSO) but insoluble in water. Our product is rigorously tested for purity (>92%) and consistency, making it ideal for precise chemical synthesis, pharmaceutical development, and material science research. Proper storage in a cool, dry place under inert conditions is recommended to maintain stability.
